Answer:
The independent variable in the experiment is A. the jar covers.
Explanation:
The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters. One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed to the independent variable). Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.
The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).
Hope this helps!
Answer:
Daughter chromosomes move toward opposite poles of the cell.
Explanation:
Prophase is the beginning of cell division. At this stage, the CHROMATIN from which the chromosomes are formed thickens and twists spirally and CHROMOSOMES are formed which become visible under a microscope.
CENTRIOLS are organelles whose main role is to form a dividing spindle during cell division, now they separate and move towards the poles of the cell.
When they reach the poles, the threads of the dividing spindle are formed between them. Chromosomes are attached to these threads.
